Modular Power Outlet with Dovetail Interlock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power outlet designs lack modular flexibility and stability when integrated into printed circuit boards, particularly for multiple outlet configurations, which can lead to insecure connections and reduced durability.
Innovation Solution
A modular outlet system comprising interlocking base, middle, and end module housings with dovetail grooves and tongues, along with secure locking tabs and lips, allowing for customizable configurations of outlets such as C13 and C14 connectors, ensuring stable assembly and secure mounting on printed circuit boards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional power outlet designs are used, then manufacturing and assembly are simple, but modular flexibility and stability when integrated into printed circuit boards are insufficient
Solution Approach 1:
The power outlet is divided into multiple independent modules, each containing a specific number of outlet cores (e.g., single-core, dual-core, triple-core modules). These modular units can be independently manufactured and then assembled in various configurations to create multi-outlet assemblies, providing flexibility while maintaining simple manufacturing processes for each module.
Solution Approach 2:
The modular design employs standardized housing structures and connection interfaces that can accommodate different types of outlet cores (e.g., C13, C14, IEC 60320 standards). This universal housing design allows the same module type to serve multiple functions by simply changing the outlet core configuration, enhancing adaptability without proportionally increasing device complexity.
2Reliability
If outlets are mounted on printed circuit boards, then electrical connections are established, but connection security and durability may be reduced without proper locking mechanisms
Solution Approach 1:
The housing incorporates pre-formed locking tabs and corresponding receptacles that are integrated into the module structure before mounting. These locking features are designed to automatically engage with the printed circuit board during the assembly process, ensuring connection security is established in advance rather than requiring additional post-assembly steps.
Solution Approach 2:
The housing acts as an intermediary structure between the outlet cores and the printed circuit board. It provides a stable mounting platform with integrated locking mechanisms that distribute mechanical stress and secure multiple outlet cores simultaneously, enhancing connection reliability without requiring complex individual mounting structures for each outlet.

AI summary
Housing for a module outlet includes first housing with a first opening configured to receive a body of a first outlet core so that a lip area of the first outlet core prevents the first outlet core from travelling through the first opening. A tab is configured to hold the body of the first outlet core secure within the first opening. A dovetail tongue is configured for sliding into a dovetail groove of a second module housing so as to secure the first module housing to the second module housing.
